He’s actually reusing some of the hardware he built for a different project. At its core is a PIC 16F628 that actuates the lights using relays. In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different patterns. This is a nice start to making the piece more interactive and we can image adding web-controlled color changes, or perhaps some Daft Punk inspired functionality.

@cyanide: although it wouldn’t work well directly hooked to the audio, per @therian’s comment, it could be cool have it driven by processed audio (extracted beats, etc.); something I’m working on for my lighting pieces in general.
